1 Slacker’s Guide to Thoracic Gross Anatomy
Prepared by Mike Ori

2 Caveat Emptor As with all slackers guides, I have omitted, condensed, and misunderstood information so don’t complain if I got something wrong, after all, you’re a slacker. Also, it goes without saying that the faculty has not vetted the information in any way. Always refer to their notes and lectures for the last word.

3 CT and Such You’re probably best off working on an interactive system try CPR Radiograph key from Slice-o lecture is important

4 Structures from labs Veins Azygous vein (c) Hemiazygous vein (c) Posterior intercostal veins (c) Pulmonary vein (c) Nerves Intercostal nerves (c) Phrenic nerve (c) Viscera Lungs Horizontal fissure (right only) (c) Inferior lobe (left and right) (c) Middle lobe (right only) (c) Oblique fissure (left and right) (c) Superior lobe (left and right) (c) Pleura Parietal pleura (c) Visceral pleura (c) Primary (main) bronchi (c,r) Secondary (lobar) bronchi (c) Superior lobar bronchi (left and right) (c) Middle lobar bronchus (right only) (c) Inferior lobar bronchi (left and right) (c) Trachea (c,r) Viscera Esophagus (c, r) Thoracic duct (c) Trachea (c,r) Bones Ribs (b, r) Sternal Body (b,r) Manubrium (b) Sternal angle (b) Xiphisternum (xiphoid process) (b) Muscles External intercostal (c) Internal intercostal (c) Diaphragm (c) Arteries Pulmonary artery (c) Subclavian artery (c,r) Internal thoracic artery (c) Anterior intercostals arteries (c) Thoracic (descending) aorta (c,r) Posterior intercostal arteries (c) Arteries and Veins Ascending aorta (c,r) Aortic Arch (c,r) Brachiocephalic artery (c,r) Right subclavian artery (c) Right common carotid artery (c) Left common carotid artery (c,r) Left subclavian artery (c,r) Descending aorta (c,r) Posterior intercostal arteries (c) Inferior vena cava (c,r) Pulmonary trunk (c,r) Left pulmonary artery (c) Right pulmonary artery (c) Superior vena cava (c,r) Azygous vein (c) Hemiazygous vein (c) Posterior intercostal veins (c) Brachiocephalic veins (c) Nerves Phrenic nerve (c) Thoracic sympathetic chain (c) Greater splanchnic nerve (c) Vagus nerve (c) Anterior vagal trunk (c) Posterior vagal trunk (c) Esophageal plexus (c) Left recurrent laryngeal nerve (c) These are set out exactly as found in the labs so there are duplicates
